Resin pipes achieve highest chlorine resistance classification

the oxidation caused by chlorinated water. As a consequence, the resins are most suitable for plumbing pipes conducting water subject to disinfection techniques. Chlorine resistance is also a requirement for some of the drinking water markets around the globe. We are extremely happy with the test results. With the proven

Dow Europe GmbH has announced that pipes manufactured with Dowlex™ 2388 PE-RT (polyethylene of raised temperature resistance) resins have received the highest chlorine resistance certification (Class 5). The certification was issued by Jana Laboratories, Canada, and conducted on pipes in accordance with the conditions specified in ASTM F20231 and ASTM F2769-102. The Dowlex™ 2388 PE-RT extruded plastic pipes were submitted to different temperatures and pressures at a chlorine concentration of 4.4 ppm and were tested for more than two years until a failure could be observed. The results allowed extrapolation to lower temperatures, and the pipes exceeded the requirement of 50 years at 60°C at such high chlorine concentration. Alex Stolarz, senior development engineer at Dow Performance Plastics, commented, “Dowlex™ 2388 PE-RT resins have a unique molecular structure which makes them highly resistant to

Using PE-RT resins can also improve recycling potential compared to alternative materials, and the reduced energy demand during processing has the potential to improve the overall CO 2 footprint of the end product.

chlorine resistance we can offer our customers a solution which enables them to extend their product offering to new markets.” Pipes manufactured with PE-RT resins have the ability to be welded, enabling connection through inexpensive, injection-moulded connectors. Surface smoothness of the end product also means reduced pressure loss and less deposit formation, meaning less maintenance is required.
